You need to find that file in the OpenCV distribution.

First, find out if and where the file opencv_core240d.lib exists on your development machine. If it does not exist then you will need to install the OpenCV library and then find out where that file is.

Once you have found that file then make sure its directory is on your project's additional library path in VS's Linker properties.
